Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed March 19, '1904. Serial N0. 199,021,

To all La7/1,0m it may concern:

Be it known that I, FRANK PHnLrs, a citizen of the United States, residing at VVellston, in the county of Lincoln and Territory of Oklahoma, have invented certain new and useful Improvements in Cotton-Gins;,and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cottongins and similar machines for separating' cotton or the is also capable ofv various modifications in de-` tails of construction and arrangement.

Without limiting myself to the particular construction and arrangement shown. the following description of the illustrated machine will serve to set forth the invention, which will thereafter be defined in the annexed claims.

In the drawings, Figure 1 is a perspective View O f the said cotton-gin; and Fig. 2 is a Vertical cross-section of the same, taken through one of the suction-passages.

The numeral 1 indicates the roll-box of the gin for holding a roll of seed-.cotton from which the lint or fibrous material is to be removed. The cotton is fed into the receivingopening of the roll-box from any suitable hopper, feed-table or other feeding device located above the gin, but not shown in the drawings.

The numeral 2 denotes the grating or breastplate; 3, the saws; 4, the brush; and 5 the brush-chamber, having its discharge-chute 6 leading to a lint cylinder or chamber 7 The opening at the front of the brush-chamber is controlled by an adjustable door or plate 8, operated by suitable devices, such as racks and pinions 9, for regulating the amount of air admitted to the brush. It will be observed that unlike the usualforms of gins the brush is located below the saws.

Back of the breastplate and saws is a waste chamber or receptacle 10, communicating with a suction tube or cylinder 11. The rear end of this chamber 10 is shown divided into two branches, each of which is controlled by a door or valve 12. The suction-cylinder 11 is in communication with any appropriate suction or blast-creating apparatus--such, for example, as a blower 13. The bottom of the chamber at its inlet end has an opening controlled by a door or plate 14, which is operated by suitable devices, such as racks and pinions 15. The saw-chamber is divided from the brush-chamber by a series of plates 16, extending between the saws from the front to the rear of the brush-casing 5. The chamber 10 is for the recovery of dirt, brush, motes, and other foreign matters from the cotton fiber, such waste substances being drawn into the suction-tube 11.

In operation of the machine the cotton fiber is caught by the saws and drawn through the grating or breastplate, separating the lint or fiber from its seeds, which are retained within the roll-box in thel usual way. The fiber adheres to the saw-teeth until it is removed by the brush 4; but as the saws rotate rapidly all dirt, motes, waste, and other foreign matters are thrown by centrifugal force from the adhering fibrous material into the chamber 10, and this action is effectively aided by the suction or blast in the tube 11, which carries off all such waste and foreign matters. By means of the valves or doors 12 and 14 the strength of the air-current can be regulated as may' be necessary. The valves 12 control the outlets from the waste-chamber to the suction-pipe, while the valve 14 controls the bottom opening at the inlet end of the chamber, regulating the amount of air drawn therethrough, and consequently the amount drawn through the saws. The plates 16 prevent the lint or cotton liber after it is brushed from the saws from being'drawn up between the saws into the waste-chamber 10. The suction-tube 11 can conveniently be extended and put into communication with the waste-chambers of a number of gins. This is but one of many forms of gins or machines to which the invention is applicable. For example, it is not essential that the cotton liber be drawn by the saws through a grating or breastplate, for the seed-cotton may be fed to the saws by any other appropriate means, such as employed in various types of gins. The grating or breastplate may also be made with its bars for separation and removal of waste, dirt, and` foreign matters either before or after the ginning operation.

I claim as my invention and desire to secure by Letters Patent of the United States4 l. In a gin or machine of similar character, the combination with the saws, means for feeding cotton or fibrous material thereto, and means substantially removed from the point of feeding for removing the adhering lint or iibrous material from the saws, of a chamber located to receive dirt, waste and foreign matters thrown from the saws between said feeding and removing means, and means for creating a suction-current in said chamber together with means for regulating said current.

2. In a gin or machine of similar character, the combination with the saws, means for feeding cotton or fibrous material thereto, and means substantially removed from the point of feeding for removing the adhering lint or fibrous material from the saws, of achamber located to receive dirt, waste and foreign matters thrown from the saws between said feeding and removing means, a suction or blast device in communication with said chamber, and a valve controlling the exit from said chamber.

3. In a gin or machine of similar character, means for cleaning the material while ginning, said means comprising provision for creating a suction air-current applied to the revolving saws, before removal of the material therefrom, means for regulating this current, consisting of a damper in the exit-liuc and a slidable door at the inlet, with means for operating both.

4C. In agin o1' machine of similar character', the combination with the saws, means for presenting the material thereto, and a brush for removing the adhering material therefrom, of a chamber behind the saws into which dirt, waste and foreign matters are ejected in advance of the brush, means for creating a suction-draft in communication with said chamber, a valve or damper controlling the exit from said chamber, and an opening and adjustable controlling-door therefor at the inlet end of said chamber.

5. In a cotton-gin or machine of similar character the combination of rotating saws, means for presenting the material thereto, a brush located beneath the saws, a waste-chamber above the brush behind the saws, means for creating a suction-draft in said chamber, and means for preveliting suction between the saws from the brush into said chamber.

6. In a cotton-gin or machine of similar character the combination of a series of saws, means for presenting the material thereto, a brush below the saws, a series of plates eX- tending between the saws from the front to rear of the brush-chamber, a waste-chamber above the brush behind the saws, and means for creating' a suction-draft therein.

7. In a cotton-gin or machine of similar character the combination of a series of saws, means for presenting the materialthereto, a brush below the saws, a series of plates eX- tending between the saws from the front to rear of the brush-chamber, a waste-chamber FRANK PHELPS.
